Referring to fig. 1 to 4, which illustrate a schematic structural view of a first embodiment of the multifunctional laryngoscope blade of the invention, the laryngoscope blade 1 comprises a tongue plate 10, and the tongue plate 10 comprises a first side wall 11, a bottom wall 13 and a second side wall 12. The first side wall 11 is connected to the bottom wall 13 and the bottom wall 13 is connected to the second side wall 12 to form a U-shaped channel a. The length of the first side wall 11 is greater than the length of the second side wall 12 in the direction of extension of the channel a. A groove 121 is provided in the second side wall 12 to guide the catheter. The opening of the groove 121 is located outside the second sidewall 12. The catheter can be an oxygen supply catheter, a drug administration catheter or a negative pressure suction catheter, and the oxygen supply catheter is used for inputting oxygen into the oral cavity of a patient so as to continuously supply oxygen in the process of examination or operation and avoid clinical complications such as hypoxemia and the like of the patient; the administration catheter can be mixed with oxygen or air for spraying medicine through the catheter so as to perform local anesthesia on the oral cavity or the throat of a patient and improve the operation tolerance; the negative pressure suction catheter is used for sucking secretion in the oral cavity or throat to an outlet cavity so as to obtain a better exposed visual field and avoid lung infection. The size of the groove 121 is adapted to the size of the catheter, for example, when a hose with a diameter of 2mm is used as the oxygen supply catheter, it is recommended that the maximum size of the inside of the groove 121 is about 2mm, and the size of the opening of the groove 121 is less than 2mm, so that the groove 121 can be stably fixed in the groove 121 without being easily detached after the flexible catheter is inserted into the groove 121. In addition, the conduit can be directly inserted into the inner space of the groove 121 from the opening of the groove 121, and does not need to be inserted along the length extension direction of the groove 121, and the conduit is not easy to push in place or fall off due to the flexibility of the conduit; when the catheter is dismantled, the catheter can be drawn out from the length extension direction; this improves the handling efficiency in mounting and dismounting.

In a preferred embodiment, the groove 121 is integrally formed in the second sidewall 12. In the present embodiment, the tongue plate 10 is made of stainless steel, and the first side wall 11, the bottom wall 13, and the second side wall 12 are different parts bent from a complete stainless steel sheet to form a U-shaped channel a; the outer side of the second sidewall 12 is recessed to form a groove 121. The inner side of the second side wall 12 may be formed with corresponding ribs; the second side wall 12 may also be thicker, without ribs on its inside, but still form a U-shaped cross-section with the other bottom wall 13 and the first side wall 11. The tongue plate 10 of the utility model is mainly suitable for clinical examination and treatment of infants.

In one embodiment, the cross section of the groove 121 may be a major arc, or the widest dimension of the inner cross section of the groove 121 is greater than the diameter of the duct, and the outer opening of the groove 121 is smaller than the diameter of the duct, so that the duct can be inserted into the groove 121 from the first end of the tongue plate 10 in the extending direction of the passage a; the conduit may also be a hose, which is inserted into the groove 121 from an external opening of the groove 121 and is clamped in a space formed by the groove. In another embodiment, the cross section of the groove 121 may also be a semicircular arc or a major arc, and at least two protrusions are required to be further included on the second sidewall 12, and the protrusions are paired and disposed beside the groove 121 to limit the catheter to be fixed in the groove 121. Thus, the catheter can be easily inserted into the detent of the groove 121 during intubation.

At a first end of the flap 10, the first side wall 11 is aligned with the second side wall 12; in operation, the first end of the tongue plate 10 is exposed out of the mouth of the patient, the second end of the tongue plate 10 extends into the mouth and even the throat of the patient, a first side wall 11 is arranged at the second end of the tongue plate 10, and the first side wall 11 is close to the upper part of the mouth of the patient.
